We look at the division of 19866733 by 458 
We want to figure out the number of times 19866733 can be divided by 458.

Moving on to step 1:
The number 458 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 458

On to step 2:
The number 458 fits into 19 0 times, leaving a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 458

Moving on to step 3:
If we divide 198 by 458, we get 0 and a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 198 and we're left with 198.
Grab the next digit (6) from the dividend, add it to 198, then carry on: 1986 / 458

Let's proceed to step 4:
458 can be fit into 1986 4 times, resulting in a remainder of 154.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 154 after subtracting 1832 from 1986.
Grab the next digit (6) from the dividend, add it to 154, then carry on: 1546 / 458

Let's proceed to step 5:
If we divide 1546 by 458, we get 3 and a remainder of 172.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtract 1374 from 1546 to get 172.
Take the next digit (7) from the dividend and append it to 172, then repeat: 1727 / 458

Moving on to step 6:
1727 divided by 458 is 3 with a remainder of 353.
The next digit of our result is 3. 
Result so far: 433.0
If we subtract 1374 from 1727, we get 353.
Take the next digit (3) from the dividend and append it to 353, then repeat: 3533 / 458

Let's proceed to step 7:
If we divide 3533 by 458, we get 7 and a remainder of 327.
Put 7 as the next digit of the answer. 
Result so far: 4337.0
If we subtract 3206 from 3533, we get 327.
Append the next digit (3) from the dividend to 327 and continue with: 3273 / 458

Let's proceed to step 8:
458 can be fit into 3273 7 times, resulting in a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 43377.0
Subtract 3206 from 3273 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
458 goes into 670 1 times with a remainder of 212.
The number 1 becomes the next digit in our result. 
Result so far: 43377.1
Subtract 458 from 670 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 10:
When dividing 2120 by 458, we get 4 with a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 43377.14
Deduct 1832 from 2120 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 11:
458 goes into 2880 6 times with a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 43377.146
Subtracting 2748 from 2880 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 12:
1320 divided by 458 is 2 with a remainder of 404.
Record the quotient 2 as the next digit in the result. 
Result so far: 43377.1462
Subtract 916 from 1320 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 13:
The number 458 fits into 4040 8 times, leaving a remainder of 376.
The number 8 becomes the next digit in our result. 
Result so far: 43377.14628
Subtracting 3664 from 4040 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 14:
458 can be fit into 3760 8 times, resulting in a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 43377.146288
Deduct 3664 from 3760 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final result is 43377.146288 with a remainder of 9.6e-06.
